1·Here we have not a bowling ball onto a ping-pong ball but we have a billiard ball.
我现在不让保龄球，去撞乒乓球，而是拿一个台球。
2·I will first bounce the ping-pong ball off the bowling ball... the billiard ball.
我首先撞击乒乓球，使它碰保龄球。，不，碰台球。
3·Now, of course, it is way harder to see that the ping-pong ball gets twice the speed of the billiard ball, because we don't do...
当然，更难看出的是，乒乓获得了两倍的速度，是台球速度的二倍，因为我们并没有做。
4·Richter thinks that rather than acting like a billiard ball, the incoming photons acted like a wave.
Richter认为进去的光子与其说像个台球，不如说更像波。
